Th all whom it may concern:

..Be it known thatvwe, EDWARD KIL- ing at New Brunswick, in the county of Middl'esex and State of New Jersey, have invented certain new and useful Improve ments in Circular-Knitting Machines; and we do hereby declare the following to be a full, clear, and exactdescription of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our present invention relates to the art.

of knitting and more particularly to the class of circular knittingmachines. It consists of an improved circular knitting machine wherein are embodied certain new constructions and combinations of parts whereby new and desirable results are produced. In the accompanying drawings we have illustrated one form in which we have contemplated embodying our said invention and the same is disclosed inthetollowing de scription and claims.

In the drawings, Figure 1 is a rear elevation of an automatic knitting machine with our invention applied thereto. Fig. 2 is a view in elevation of the left end of such machine. Fig. 3 is a top or plan view of the lever engaging the pattern cylinder. Fig. 1

Figs. 22 and 23 are partial sectional views showing modifications of the cam cylinders.

ln the knitting of seamless hose of the open or lace work pattern, it is desirable to ave? open or lace work begin below the top of the leg of the stocking so that in case of 'full hose, a strong hem or welt can be. se-

cured, and in both full and half hose it is desirable that a strong and durable union at the toe may be readily made. It is also desirable to knit the opener lace work on the back of the leg of the stocking, and yet be able to knit the heel and bottom of the foot and toe of the stocking of solid plain knitting and to knit solid plain knitting on the top of the foot of the stocking before reaching the toe, so that there shall be solid plain knitting onboth sides of ,the closure ncar the toe of the stocking. These results we accomplish by the improvements herein set forth and we also are enabled to knit drop stitch open work, lace work and solid plain knitting in any order or in such proportions as may be desired; to change on the back of the leg to solid plain knitting when desired without changing the work on the front of the leg of the stocking; and We are also able to knit a different pattern of open or lace work on the back of the leg from that on the front of the same. We can also knit tuck stitch, open lace work or solid plain knitting in any order or sequence upon ting machine shown and described in the patent to E. E. Kilbourn No. (569,730 granted Mar. 12, 1901, andhis earlier Patent No.

- 679,281 July 23, 1901, and we prefer to use our devices when applied to' such a. machine but we desire it to be understood that the principle of our invention and many of its details can be used-in connection with other forms of knitting machines.

The knitting machine to which our novel features of construction are applied is provided with two cam cylinders, each actuating and controlling approximately one-helf of the needles of the needle cylinder. The up- I cylinder A are shown in Fig. 11, while Fig.

13 shows the cams of cam cylinder B.

In Fig. 11, C is the knitting cam which is fixed and immovable. Theside of. this cam next to the interior wall of the cam cylinder is recessed to receive the sliding cam C. This cam has a projection which extends outwardly through a slot in the cam cylinder and to this pro ection is secured the plate 0 which is provided with a pine. The pin 0 is engaged by the bifurcated end of a short lever o see Fig. 12, pivoted to a plate a secured upon the upper edge of the cam cylinder. The lever '6 is provided on one side Wit% the cam lug c and has its opposite si e engaged by the free end of a spring 0% whose rpposite end is secured to the cam ring. On the side of the lever 0" which is provided with the cam .lug c is the lever C which is pivoted to the cam ring. or to some part rigidly connected thereto. The free end of this lever normally rests above the cam projection c and is provided with an outwardly extending projection 0". A spring c bears .upon the free end of the lever C and tends/to press; the same downward and to hold it down when in a depressed position. By pressing the lever downward, its free end'engages the cam lug c and forces the free end of the lever 03 to the right as shown in Fig. 12 and moves the slide a and cam C' to the right or to the position shown in Fig. 11. Vhen forced to this position the lever C becomes a lock holding the lever a and cam C in the positions shown in Figs. 11 and 12 until the lever C" is raised to its upper position and the spring 0 tends to hold the lever from accidental displacement. The plate a is provided with a lug a to en- ,gage the lever C" and limit its upward movement.

The needles which knitthe back of the leg and thehgehhottom. of the foot and toe of mally rest upon ledge a. Thenibs of these needles are of two lengths, a path having nibs long enough to engagethe cam C when in the position shown in- Fig. ll, theothers having a shorter nib which will only engage the cam C. Of these needles those having the shorter nibs do not engage the cam C and at every revolution of'the machine knit a plain stitch.

The machine referably knits with what is termed a short cad, that is, with the thread guide but a short distance in advance of the knitting cam, or the knitting point. These needles take the thread at about the point x and are immediately drawn'downward to make the stitch. The other, and longest nibbed-needles before reaching the point so, when the cam C is in the position shown in Fig. 11, engage such cam and are drawn downward before the thread guide has reached the point at which such needles would normally take the thread and continue is in the sameposition, continue to engage the cam C and do not take the thread though otherwise going through the movements of. knitting. v The needles having the shortest nibs and which said nibs normally rest on lodge a are at such height that the thread will be laid against such needles below the. hook of the same on each revolution of 'thc machine, but as the latch is below the loop on the needle they will not knit when depressed by the cam C. When it is desired to have such needles knit, their nibs will be raised-to the level of the lodge a by the cam C. This cam when in its depressed position will have the apex of the cam on a level with or slightly raised and the latches of the same brought above the loop and threads on such needle and such needle will then take the thread at the point 2? and .knit a stitch locking the threads that have been laid below its hook, thereby forming tuck stitch knitting,

The. cam C is connected witha block slidinz in a, guide way in the cam cylinder and such block is operatively connected with the the bifurcated end of the lever lever c. In this instance the said block is provided witha pin 0 which engages 1s lever is provided with an outwardly extending projection 41 by which the lever is moved to raise or lower the cam C .When the cam C is moved behind the cam C and the cam C is'maintained in its elevated position, the machine will when revolved, knit solid plain knitting with all the needles actuated by the upper cam ring. When it is desired torecip- "locate the cam cylinder to produce reciprocating knitting, another cam C of like construc-tion will be raised" to the level of the ledge a. This cam is raised and lowered by a lever 0 provided with a projection 0, similar to the lever for operating the cam C. A spring 0 bears upon the upper side of the lever 0 and tends to maintain it in its lower position.

The arrangement of cams in the lower cam cylinder 13 is'simpler, for as the needles operated by this cam -cylinder do not knit during reciprocating. knitting, provision for such knitting is omitted. This cam cylinder is provided on the inside with the knitting cam D, which like the cam C of the upper cam cylinder may engage all of the needles provided with nibs for this cylinder. As in the case of the cam cylinder A, the needles of this camflcylinder are divided into three classes havingnibs of different lengths. The shorter nibs are normally raised by the riser cam d to the height only of the ledge b. This does not raise the latches above the loops upon the needles, and as the thread guide and cam D approach these needles the thread is laid across the needles below the hook, the cam D then depresses them but owing to the latc'lrbeing below the loops on the needles, the needles do not cast off. The other needles are provided with nibs of different lengths butboth are raised by the riser cam to the heightof the ledge b in which position the latches are above the needle loo s. The cam Dis directly below the cam C of the upper cam cylinder A and as D approaches these needles they take the thread at the same point and are forced cured the slide (1 moving in a guide/way on the outside of the cylinder. This slide is provided with the cam faced end (1. A lever (l is pivoted to the cylinder having its free end normally above the cam faced end of the slide d and said lever is provided with an outwardly extending lug (Z. A spring (l is so connected to the slide d as to force'the -ward it engages the cam face of the slide d slide beneath the free end of the lever d when such lever is in its raised position. In this position of the lever and slide the cam is in its retracted position behind cam D. By forcing the free end of the lever 03 downand forces it to the right (see Fig. 14) and moves the cam D out from behind the cam D and into the position shown by dot'ged lines. When forced to this position the cam and lever are locked as at such time the spring d tends to move thelever-downward. In this position the cam D' will engage the longer nibbed needles of the ledge b and begin to depress them before they have taken the thread from the thread carrier. It then moves them downward and causes them to cast off the loops, if any, that may be on them thereby dropping their stitches.

I) is an auxiliary riser cam which engages only the nibs of the needles which rest on ledge 7) and engages these only when in a raised position. This cam is se-- cured to a slide in a vertical guide way in the cylinder, and this slide has a projection al -extending outwardly beyond the cylinder by which the cam may be raised and lowered. When this cam D is in its raised posi= tion, and the cam l) is in its retracted position, all of the needles take the thread from the thread guide and knit a course of plain stitches at every revolution of'the'machine. When the cam D is in its lower or inop erative position the needles that are raised only to the height of ledge 11' are not raised ,100 high enough to bring the latch of the needle above the loop on the needle and the downward movement of such needle by the cam D does not cause it to cast off its loop as W the latch closes upon the thread in' the hook. The needle is, however, raisedto such a position that at every round of the thread guide a thread is laid across the needle below the hook and above-the latch.

The needles of the needle cylinder are di- 'with nibs to engage the cam construction of thevlower cam cylinder B.- 'It will thus be seen that at each rotation of-' the machine the cams of cylinder 'A are for approximately one-half of its revolution out of con tact. with the nibs of the needles that are actuated by it. It is during this period of the revolution of this cam cylinder that the cams are moved from one position to the other. 136

. ferent lengths to engage therewith. E is a stationary ring or casing which extends wholly or partially around the upper cam cylinder. It extends around the needle section operated by the upper cam cylinder,

and a little beyond each edge of the section. This casing E is provided on its inner side with a ledge or flange 6 extending inwardly toward the cam cylinder. A cam plate 6' is pivoted in line with this ledge or flange and a spring a serves to normally keep it in a depressed position. 'The inner side of this cam plate is flush with the inner face of the flange 6. At the other end of the flange is pivoted the cam plate 0 This cam plate is of half the thickness of the flange e and is so mounted that its outer side is against the inner side of the casing E, and therefore, extends inwardly only half the width of the flange- The cam C isto be operated only during reciprocating work. ilhe projection o to operate such cam is of such leigth that it does not engage with the cama'plate cand as the cam cylinder is rotated in the direction shown by the arrow in Fig. 20, the projection c passes under the flange 6. This flange, as will be seen, prevents the ac cidental shifting of-the cam during the period that the active cams of the upper cam -cylinder. are in engagement with their plate is thrown down to itsnormal position same.

by the spring e. As longas this operation is' continued, the cam C therefore remains in its depressed position.

When reciprocating work is begun on the first movement of the cam cylinder in a direction the reverse of its regular rotation, the projection engages the cam plate e and is raised upon the flange e which holds the lever 0 and the cam C in their elevated positions. During this movement the cam C is in rear of the cam C and the needles after knitting are all raised to the level of the ledge. As soon as the projection 0 leaves the ledge e the lever c is depressed by the spring bearing upon the On the return movement the cam C is not needed and the projection 0' .passes below the ledge e and cam plate 6 and on its nextmovement it is again raised by the cam plate a and held during the period that it is required to be raised by the ledge or flange 6.

The cam plate 6 see Fig. 17, is rigidly secured to its pivot and on the outside of the casing E, such pivot has the arm a secured thereto; this arm is connected b tions as hereafter set forth, wit pattern mechanism which control fthe position of the cam plate and the cam C. When the arm 6 is moved and the point of the cam plate is raised,the projection c of lever 0 connec will. engage the underside of the cain plate is passing from one-end of the flange e to the other thecam is free. from allpressure which would serve to move it downward and it, therefore, remains in position. Should it he accidentally moved, however, the cam plate e would again raise it before it would engage the needles. During reciprocating work, cam plate'e isheld in position to raise the cam C downward movement would be raised by cam plate 6 when movingv in one direction; 5

and by cam plate e when moving in the other. In either case the camwould be held up by the ledge or flange e. A-- further cam plate e see Figs. 15 and 20, is provided for moving cam G into and out of operative position. This cam plate has-an arm 3 secured to its pivot'and this arm is connected with pattern mechanism by which it is controlled. When this cam is turned and its point raised, theprojection c" willengage' the underside of the' cam plate and the lever C" will be depressed, moving the cam G into operative position.

ection c of the lever C engages the upper side of the same, the lever C will be raised and the spring 6 will draw the cam back into inoperative position. The projection c is of such length that the camplate cis placed out ofthe path of the pro ections which actuate the cams C C and therefore, the cams C and C ;'are never affected there- Such cam in case of accidental When this cam plate 6 is moved downward so that the pro-- by, as the, projection c in a plane above that of the projections c r and c, cam C is not affected by theother eam plates for this cylinder.

For controlling thc cums D and D of the lower canr ylinvlcr, certain other com plates are provided. The needles actuated by the lovvcr mun cylimlcr occupy the oppos ii half of the needle cy inder from those actuated by the upper 1.1m cylinder, thereforc, the cum plates for moving cams l) and l) are on the opposite side oi? the. machine from ill upper cylinder.

In the present instance, these cam plates are controlled hy the following instrumentalities.

As shown in Fig. 1 the machine near one end is proiided with :1 pattern cylinder Gr which cylinder is mounted on ashaft G, extending transversely of the machine. The pattern cylinder is provided at one end with the ratchet G by which it is revolved, through pawl g. This pawl has its upper end hcokcd'and engages a cam or eccentric j on the transverse shaft J through which motion is conveyed to the cam cylinder and is caused to have one reciprocation and move the pattern cylinder the distance of one tooth of the ratchet at each revolution of the cam cylinders. This pattern cylinder is provided with a spiral groove extending from one cnd to the other of the cdindcr and in such groove, the cylinder is provided with holes 9 to reccivo pins 5 A bracket G is secured to the left end of the frame of the machine, see Figs. 2, T and 9. This bracket sup orts a rod G rigidly secured to said brac'et. viclcd with :m elongated huh g is pivoted upon. the: rod (1 so that it is free to swing and slide Lippi; said rod. The true cnd f the lever has a downwardly extending; projection of such vvidt i as to enter the groove of the 'mttern cylinder. The free end of the lever (i is extended laterally in both directions and at each end is provided with an upwardly extending car in which rigidly mounted a rod 9'.
